Try adding the following CSS to your Quick CSS (located under the Styling Tab in the theme options) or the custom.css file in the css folder of your theme files:

.small_header_info {
color: #D53030;
}

The dots however you would need to change the image in the theme files. It will be images>layout>dots_dark.png and if you save that file on your computer and then edit it you can upload it to your server in the same place and it will then show up differently site wide.

You can only change the color of the social icons manually. Go to wp-content/themes/eunoia/images/icons folder then look for the icons and edit the color manually using photoshop or any other image software you’re comfortable with.
